Amazing UFO (The Best Footage EVER!)

I dont believe in ufo’s but what I filmed in the sky through my iphone gives me the chills everytime i think about it, I dont know what it was but the way it moved the speed and accelaration I just dont know, leave me your thoughts or comments, sorry about my baby crying in the back ground I was so in shock that i couldnt hear her crying until after i lost site of the flying object. Filmed Sydney Australia 31st March 2010….
